' NUT,

1 0 all whom it may concern:

Be it known that I, THADDEUS KINNEY, a citizen of the United States, and resident of Milwaukee in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Nuts; and I do hereby declare that the following is a full clear, and exact description thereof.

lVfy invention relates broadly to new and useful improvements in nuts, especially those which have particular application to caps for pneumatic tire valves.

It is the principal object of this invention to provide a nut which can be readily slid longitudinally of abolt or the like having mutilated threads, or operated to rotatably engage said threads.

It is well known that the exposed portion of the valve stem ofa pneumatic tire valve is of considera l length and that it requires an appreciable amount of time to thread the protecting cap thereon in the ordinary man- To allow rapid manipulation of the cap, the same is normally provided/with in.- .terrupted threaded portions adapted to slid- --ably cooperate with the flat faces or thread- ]ess portionsof the stem. With this arrangement the cap can only be rotated a portion of a revolution with the threads thereof in codperation with the threads of the stem so that frequently the proper tight engagement cannot be procured between the" end of the cap and the portion of the wheel felly surrounding the'stem.

One of the objects of the invention is to so associate the improved nut with a valve cap that the same may either be slid longia tudinally of the stem or moved the entire length thereof with the threads of the two parts (the cap and the stem) in cooperative engagement.

A further object is to provide means for selectively holding the movableparts of the cap to procure either of the movements described in the above paragraph.

With these general objects in view, the invention resides in the novel features of construction. combination and arrangement of parts which will be hereinafter more particularly described and claimed, and shown in the drawing in which:

Figure 1 represents a portion of the folly and tire of a Wheel and the means for permitting inflation of said tire, said means being partly in section. v Fig. 2 s adetail transverse section taken Specification of Ztetters Patent.

Fi 5 is .a sectional view similar to Fig. am taken on the plane of the line 5-5 of i 4. nasmuch as my invention is esgecially appneumatic valve stem thereof has been illustrated. It is to be understood, however, that the principal feature of the invention, namely the two-part nut having means for increasingthe thread area thereof, may be used in various other arts, and many changes may be made therein without departing from the principles of the invention.

Referring to the depicted embodiment of the invention, F indicates the felly of a wheel on which a pneumatic tire T is mounted and through a radial opening 0 in the former extends a threaded valve stem 1. As is customary in devices of this character, the stem is provided with two longi-' tudinally extending diametrically opposed flattened and threadlcss portions 2.

Normally the stem 1 is protected by an elongated tubular cap 3; the washer 10 in the For cooperative engagement with either threads on the stem 1 or the flattenedportions 2 thereof, the cap 3 carries an inner thread portion 4 and an outer thread por tion 5. When the cap is to be slid longitudinallyi of the stem for rapid application of the former to the latter, these thread portions 1 and 5 are longitudinally alined as in Figs. 4 and 5. But when the cap is to be rotated on the stem and the threads of the latter cooperatively engaged, the thread portions 4 and 5 are disalined as in Figs. 2 and 3.

It will be noted that there are two diametrically opposedthread portions 4 formed on the inner wall of the cap adjacent lts inner end. This inner portion of the cap 18 also provided. with an outwardly extending radial flange 6, which is circular in plan view and receives the similarly shaped end 7 of an inner shouldered collar 7. The shoulder of this collar 7 engages the outer end of the cap andtheadjacent side of the den e 6, a

The outer end 7" of the collar 7 or that part extending in the opposite direction from: the shoulder to the part 7 is of an internal diameter substantially equal to that of the cap 3 and carries a pair of diametrically opposed restricted thread portions 5.

Theicollar"? is-held in position by a retaining collar 8, from the ipner end of which extends a radial flange 9 for engagement withthe inner side of the flange 6. This collar is substantially polygonal in plan view to permit of the application of the wrenchto-thelcap, and its free end is spaced from the adjacent end 7 of the collar? to form apacking seat in whichan annular gasket lfllisdisposed.

From this description it will be seen that when the-cap is-to'be applied to a threaded stem, thethread portions 4 and 5 are alined by rotating the flange 7, and. consequently the flangeS a predetermined distance in one direction. portions 4 and 5 when alined is equal to or slightly less than the width of the threadlessportion 2,,the cap may readily he slid longitudinally of the stem 1 without interruption. As soon, however, as the collars 7 and 8 are rotated in the reverse direction, the severaltliread portions 4 and 5 will be disalined threadareaof the cap'will be considerably wi er than the threadless portion of the stein '1 and the only way in which said cap canbe moved on said stem is by rotatioii'ot the former, as in the case of any ordinary not, The thread portions 4 and 5 maythus be disalined before the cap is placed over thestem, or after this operation and when the washer of the cap is adjacent the telly F, As a means for positively holding the thread portions in either their alined or in their disalined positions, I provide the cap with a spring finger 11 adapted to engage in either of two spaced seats 12 and 13 cut or pressed in the edge of the retaining collar 8. From Figs. 2 and 4 it will be noted that when the finger 11 is .in the seat 12, the thread portions 4 and 5 are alined and when it is snapped into the other seat 13 said portions are disalined and the thread area doubled in width.

The combination with a threaded valve stem having a longitudinally extending 'threadlcss portion of restricted width, of a cover cap removably disposed over the stem, one end of the cap being closed and the other end open, a thread portion of restrict- Since the width of the thread as in Figs. 2 and 3, whereupon the.
